Objective To investigate the mechanism of traditional Chinese medicine (TCM) Sheshang capsule for treatment of blood coagulation dysfunction in patients bitten by Trimeresurus stejnegeri snake. Methods A prospective study was conducted. Seventy Trimeresurus stejnegeri snake envenoming patients whose manifestations conformed to the diagnostic criteria of the fire toxin syndrome in TCM were assigned into therapy group and control group by random number table (each, 35 cases). The basic treatments (including wound disinfection, intramuscular injection of 1 500 U tetanus antitoxin, conventional dose of antibiotics, 10 mg dexamethasone, 40 mg omeprazole) and 10 Jidesheng Sheyao tablets three times a day were applied in the control group. In the therapy group, the basic treatments the same as those of the control group were given, and in the mean time 5 Sheshang capsules (the drug was prepared in our hospital including ingredients:rhubarb, coptidis rhizoma, pleione bulbocodioides, elecampane inula root, bayberry bark, borneol and so on) were administered three times a day. The therapeutic course in the two groups was 1 week. The levels of platelet α-granule membrane protein (CD62p), thromboxane B2 (TXB2), platelet factor 3 (PF3) and von Willebrand factor (vWF) in serum were measured by enzyme linked immunosorbent assay (ELISA) before and after treatment. Results Before treatment, there were no significant differences in CD62p, TXB2, PF3 and vWF between therapy group and control group [CD62p (μg/L):3.81±1.64 vs. 3.52±1.43, TXB2 (μg/L):13.04±1.67 vs. 13.31±1.14, PF3 (μg/L): 2.84±1.08 vs. 2.88±1.23, vWF (μg/L):12.36±2.42 vs. 11.89±2.08, all P>0.05]. After treatment, the levels of CD62p, TXB2 and PF3 were increased, while vWF decreased compared with those before treatment in both groups, the level changes in therapy group being more remarkable [CD62p (μg/L): 6.73±1.77 vs. 5.81±1.62, TXB2 (μg/L):18.65±1.77 vs. 17.90±1.68, PF3 (μg/L):5.61±1.48 vs. 4.77±1.24, vWF (μg/L):3.87±1.01 vs. 4.58±1.09, P < 0.05 or P < 0.01]. Conclusion The Sheshang capsule is capable of treating patients with blood coagulative disorder after Trimeresurus stejnegeri snake bite, and its mechanism is possibly related to the improvement of platelet activation function and amelioration of the damage of vascular endothelial cells.

Objective To investigate the influence of the purging fire and removing toxin method on chemokines and adhesion factors related to vascular endothelialitis injury induced by toxin of trimeresurus stejnegeri bite.Methods ① Animal experiment:50 healthy New Zealand white rabbits were chosen.According to random numbers generated by statistical software,they were divided into normal control group,model group,low,middle and high dose Sheshang capsule groups,10 in each group.Trimeresurus stejnegeri bite model was replicated by injecting 0.75 mL/kg snake venom into subcutaneous tissues of rabbits' right hind legs.And the same volume of normal saline was injected into the rabbit in the normal control group.After the model was established for 6 hours,the rabbits in low,middle and high dose Sheshang capsule groups received 174,348 and 522 mg· kg-1 · d-1 of Sheshang capsule solution respectively (the content of capsules was dissolved in normal saline to make liquid with 17.4,34.8 and 52.2 g/L Sheshang solution respectively,so the volume of gavage of each group was 10 mL· kg-1 · d-1);in the model and normal control groups,the same amount of normal saline was given by gavage,once daily for consecutive one week.24 hours after the last gavage,the blood of the rabbits was collected through an auricular border vein and the serum was separated by centrifuge ready for use.Meanwhile,the whole abdominal aorta segment of the rabbit was harvested and kept them in liquid nitrogen ready for use.② Cell experiment:human umbilical vascular endothelial cell (HUVEC) was cultured with MEM for 24 hours.The solution was replaced and according to the random number generated by statistical software,the cells were divided into blank control group,model group and low,middle,high dose Sheshang capsule medicinal serum groups,10 wells in each group.Trimeresurus stejnegeri toxin cell model was reproduced by addition of 5 mg/L snake venom into the cell culture medium.After 6-hour culture,the cells of model group and blank control group received 10％ normal rabbit serum,and the cells of low,middle and high dose Sheshang medicinal serum capsule groups received serum containing 5％,10％ and 15％ drug,respectively.After culture for 72 hours,the cells were collected and the total RNA was extracted.The real-time fluorescent quantitative polymerase chain reaction (qPCR) was used to detect the levels of mRNA of interleukin-8 (IL-8),monocyte chemoattractant protein-1 (MCP-1),intercellular adhesion molecule-1 (ICAM-1) and vascular endothelial cell adhesion molecule-1 (VCAM-1) in the vascular endothelial cells of rabbit aorta abdominalis and human umbilical vein,and the content of serum E-select element (CD62E) was measured by enzyme linked immunosorbent assay (ELISA).Results In model group,the expression levels of mRNA in IL-8,MCP-1,ICAM-1,VCAM-1 and the content of CD62E were all increased significantly in the endothelial cells of rabbit aorta abdominalis and HUVEC compared with those in control group [when the mRNA expression levels of IL-8,MCP-1,ICAM-1 and VCAM-1 in normal and blank control group were all being 1,the mRNA expression levels (2-△ △Ct) of the above mentioned inflammatory factors and adhesion molecule in animal model group were 3.96 ± 0.39,3.07 ± 0.27,3.71 ± 0.26,3.94 ± 0.26,and the mRNA expression levels (2-△ △Ct) of the above mentioned inflammatory factors and adhesion molecule in HUVEC model group were 3.53±0.70,2.24±0.48,3.13±0.44,2.80±0.13,respectively,all P ＜ 0.01].The content of CD62E in serum was increased significantly in model group compared with that in normal control group (μg/L:1.31 ± 0.22 vs.0.82 ± 0.13,P ＜ 0.01),the mRNA expression levels of IL-8,MCP-1,ICAM-1 and VCAM-1 were decreased significantly in low,middle,high dose Sheshang capsule groups compared with those in model group in endothelial cells of aorta abdominalis of rabbits and HUVEC [abdominal aorta:IL-8 mRNA (2-△ △Ct) were 1.13 ± 0.19,1.26 ± 0.16,1.27 ± 0.17 vs.3.96 ± 0.39,MCP-1 mRNA (2-△ △ Ct) were 1.79 ± 0.24,2.22 ± 0.38,1.76±0.19 vs.3.07±0.27,ICAM-1 mRNA (2 △△Ct) were 2.05±0.11,1.68±0.09,2.37±0.48 vs.3.71±0.26,VCAM-1 mRNA (2-△△Ct) were 1.59±0.08,1.40±0.11,1.84±0.11 vs.3.94±0.26;HUVEC:IL-8 mRNA (2-△△Ct) were 2.33±0.59,2.82±0.82,2.51±0.77 vs.3.53±0.70,MCP-1 mRNA (2-△△Ct) were 1.59±0.35,1.48±0.36,1.54±0.29 vs.2.24±0.48,ICAM-1 mRNA (2-△△Ct) were 1.46±0.38,1.77±0.65,1.73±0.50 vs.3.13±0.44,VCAM-1 mRNA (2-△△Ct) were 2.49±0.24,2.18±0.19,2.45±0.24 vs.2.80±0.13,all P ＜ 0.05].The contents of CD62E were decreased significantly in middle,high dose Sheshang capsule groups compared with the content in model group (μg/L:1.01 ±0.14,1.04±0.13 vs.1.31 ±0.22,all P ＜ 0.01),but there were no statistical significant differences among the three drug group (all P ＞ 0.05).Conclusion The therapy of purging fire and removing toxin can treat vascular endothelial injury by inhibiting the inflammatory response induced by Trimeresurus stejnegeri bites.

Objective     To analyze the effects of systematic lymph node dissection (SLND) and lobe-specific lymph node dissection (L-SND) on perioperative and long-term outcomes of patients with clinicalⅠA (cⅠA) stage lung adenocarcinoma. Methods     A retrospective analysis was done on the patients with cⅠA stage lung adenocarcinoma who received thoracoscopic radical resection admitted to the Affiliated Hospital of Qingdao University from January 2013 to August 2016. Propensity score matching was conducted to eliminate the biases. The recurrence-free survival was compared between the two groups after matching. Perioperative parameters and postoperative complications were also analyzed. Results     A total of 725 patients were enrolled, including 252 males and 473 females, with a median age of 62.0 (31.0-69.0) years. There were 228 patients in the L-SND group and 497 patients in the SLND group. After matching, there were 211 patients in each group and no statistical difference in the incidence of postoperative complications (10.9% vs. 13.7%, P=0.374), identification of metastatic positive lymph nodes (12.3% vs. 9.0%, P=0.270), or recurrence-free survival (P=0.492) were found between two groups, whereas the operation time (163.9±39.4 min vs. 135.4±32.4 min, P<0.001), intraoperative blood loss [100.0 (20.0-800.0) mL vs. 100.0 (10.0-400.0) mL, P<0.001], intubation time [4.0 (1.0-18.0) d vs. 4.0 (1.0-9.0) d, P<0.001] and hospital stay (12.3±3.3 d vs. 10.8±2.4 d, P=0.003) in the SLND group were found to be significantly higher or longer than those in the L-SND group. Conclusion     L-SND has a similar efficiency to SLND in terms of postoperative complications, pathological lymph node metastasis, and recurrence-free survival, as well as significant advantages in reducing intraoperative blood loss, and shortening operation time, intubation time and length of hospital stay. Therefore, L-SND can be recommended to replace SLND as a method for lymph node resection in patients with cⅠA stage lung adenocarcinoma.
